Title: Improvements in and relating to flight indicators for aircraft
IPC: G01C19/44
Filed: 1943-11-09
Abstract: 599,607. Gyroscopic apparatus ; magnetic compasses. SPERRY GYROSCOPE CO., Inc. Nov. 9, 1943, No. 18608. Convention date, May 27, 1942. [Classes 97 (ii) and 97 (iii)] A gyrovertical is provided with horizontal gimbal axes inclined at an angle to a vertical plane perpendicular to the front face of the instrument so that no gimbal pivot obstructs the view of the interior parts. As applied to an instrument for giving an indication of the bank and pitch attitude of an aircraft and also the heading in azimuth, the gyro rotor 31, Fig. 2, is mounted within a case 26 having at the base a U-shaped frame 27 terminating in the athwartship or minor axis trunnions 25, 29. These trunnions are supported in a C-shaped gimbal ring 15, Fig. 1, journalled in bearings 18, 20, the open side of the ring being located behind the window 11 so as to permit of an uninterrupted view of the indications (showing headings in azimuth and an artificial horizon) inscribed on the sides of an inverted cup-shaped compass card 44 carried inside the gimbal frame 27 and mounted on a jewelled pivot 48 upstanding from the gyro case. The indications are situated in the stabilized plane through the point of intersection of the gimbal axes, and are read against lubber or comparison lines. On the top of the compass card are two permanent magnets 45 and a further set of reading indications 46. The rotor may be driven by air directed against buckets 34, and erected by pendulous shutters 42, 43. To avoid inductive magnetic coupling between the compass magnets and the rotor, the rotor is constructed of inert material or may be of the non-inductive type such as that described in Specification 574,848. Oscillation of the compass card is damped by the inductive magnetic coupling between the magnets and the rotor case. If the instrument is intended solely for use as an artificial horizon, the side indications may be placed directly on the rotor case. Specification 599,665 also is referred to.

Filed: 1917-12-19
Abstract: 121,522. Ransomes & Rapier, and Cra cknell, R. J. Dec. 19, 1917. Refrigerating, compression machines for, of the type comprising co-axial rotary casings forming a condenser and evaporator, one of the casings containing the compressor. A rotary compressor is employed similar to that described in Specification 121.518, [Class 110 (i), Centrifugal and screw fans &c.], and comprising one or more rotors having helical channels around their peripheries and arranged in an eccentric rotating drum containing a liquid acting as a piston. The casings A, B forming respectively the evaporator and condenser are closed at their inner ends by covers A<2>, B<2> connected by a cylinder F serving as a distance member and forming an insulating chamber. The compressor may be arranged either in the condenser or in the evaporator, or a compressor may be arranged in each, to obtain two. stage compression. The liquefied refrigerant passes from the periphery of the condenser to the periphery of the evaporator through a pipe M having its ends bent outwards radially, the flow being controlled by centrifugal action and the difference in pressure. The condenser rotates in contact with cooling water and the evaporator in contact with brine. The rotors G of the compressor are formed with a wide channel G<3>, Fig. 3, with parallel walls G<10> for one turn, and a narrow channel G<4>, shallower than the first, for a second turn, one rotor being right handed and the other left handed. They are spaced apart by crescentshaped parts G" serving to deflect liquid refrigerant on to the shaft away from the opening C<1> leading to the condenser through a hollow portion of the shaft. The drum J is mounted on ball bearings on eccentrics K held stationary by a weight K<2> and themselves mounted on ball bearings on the shaft. Sleeves J<2> with flared ends J<3> project towards the rotors and prevent the escape of liquid even if the shaft is tilted. The refrigerant employed may be ethyl chloride, and mercury may be employed as the liquid in the drum. Gas from the evaporator casing passes through passages K<3>, K<4>, to an opening G<9>, Fig. 3, in the outer wall of the rotor channel, and is delivered through the central space between the rotors to the openings C<1> in the shaft. The two rotors may be replaced by a single rotor having channels running in the same direction, and the inlet and outlet openings for gas may be distributed around the rotor to equalize the pressure on the rotor. The weight K<2> may be fitted with a scoop to deliver refrigerant over the drum to cool it, and the condenser may be formed with internal radial ribs or fins. The space formed by the cylinder F may be evacuated, and the whole apparatus is exhausted before being charged with refrigerant.

Title: A method of making mercury switches
IPC: H01H29/18
Filed: 1934-06-27
Abstract: 423,708. Mercury switches; electromagnetic switches. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Adlake Co. ; 319, West Ontario Street, Chicago, U.S.A.) June 27, 1934, No. 18980. [Class 38 (v)] In a method of making gas-filled mercury tube switches, the mercury and other parts are inserted in the open - ended tube or envelope, which is then connected by its open end to an apparatus which fills it with gas at the required pressure; the switch is then tested without sealing the open end, and if unsatisfactory further adjustments are made and the filling and testing processes repeated before the open end is finally sealed. The method is specially suitable for making switches of the kind shown in Fig. 2 in which circuit is made or broken between contacts 11, 12 by the rise or fall of mercury in the tube 10 caused by the descent or ascent of an iron tubular core 15 when a magnet 16 is de-energized or energized. A delayed action is provided by a hole 23 in the core which is partially closed by an adjustable wedge 24, and which allows the gas to pass slowly through. In such a switch adjustment of the amount of mercury and of the wedge 24 will be necessary. Fig. 1 shows the tube 10 connected by a restricted tube 32 and heavy rubber tubing 34, 35 to a cock 30 which can put it into communication either with a vacuum pump 28 or a gas cylinder 47. A luminous discharge tube 31 is also provided to indicate the degree of vacuum. By these means the tube is first evacuated and then filled with gas. It may then be tested either by putting a solenoid round the tube where it stands, or by sealing off the tube 32 at 33 and then taking the tube 10 away for a test. If adjustments are found necessary these are made and the tube 10 again connected to the apparatus by means of another tube 32 for exhausting and filling. For mass production a number of switch blanks may be placed on a rotary table.

Title: Process for Removing Sulphur Dioxide from a Gas
IPC: C01B32/40
Filed: 1968-04-23
Abstract: 1,160,197. Removing sulphur dioxide from gases. LUMMUS CO. 23 April, 1968 [24 April. 1967], No. 19188/68. Heading C1A. Sulphur dioxide is removed from a gas by contacting the gas with a metal carbonate to produce a metal sulphite, the carbonate being regenerated by reacting the metal sulphite with carbon monoxide to give the carbonate, carbon dioxide and sulphur. In the described process (see Figure) a gas containing SO 2  is passed via 10 into absorber 11 charged with an alkalimetal or alkaline-earth metal or zinc carbonate at 250-1000 F., the purified gas being passed out via 26. After a period of time absorption of SO 2  in 11 is stopped, and the gas instead passed into a similar absorber 12. The absorbent in 11 is then regenerated at 1000-1800 F. with carbon monoxide to give carbonate, sulphur and carbon dioxide. The gaseous sulphur is condensed in 30 and 34, while the CO 2  is reduced to CO by a carbonaceous material, such as coke, in 37 and may be reused in the regeneration. Any SO 3  in the SO 2 - containing gas is removed in the process by reaction with the carbonate to a metal sulphate, but reduction with CO reduces the sulphate only to a metal sulphide. Thus additional metal carbonate has to be added to 11 and 12 at intervals. The process is run so that while 11 is absorbing, the material in 12 is regenerated and vice versa. The difference in temperature between 11 and 12 means that after absorption the material in a reactor must be heated, for example, by a hot gas, and after regeneration the material must be cooled, for example by a blast of cold air.

Title: Body colour or top finish for leather
IPC: C08L89/00
Filed: 1953-07-10
Abstract: An aqueous composition for finishing or colouring leather comprises an emulsified oil, fat, or wax, a condensation product of a soluble protein or protein degradation product with a higher fatty acid, resinic or naphthenic acid, or a higher aliphatic or aliphatic-aromatic sulphonic acid, and, in the case of a colouring finish, an organic or inorganic pigment or dye.  A protein such as albumin, gelatine, globulin, or casein, which may be solubilized with ammonia, may also be added.  The condensation product may be obtained by reacting solutions of water- or alkali-soluble proteins such as size, gelatine, casein, albumin, globulin, or cleavage products formed by the hydrolytic decomposition of proteins such as protalbic or lysalbic acid with a halide of the selected carboxylic ar sulphonic acid in the presence of acid binding media.  Suitable acids are dodecyl benzene sulphonic acid, or fatty acids having straight or branched hydrocarbon chains of 10-20 carbon atoms, e.g. soya or peanut oil fatty acids.  The oil, wax &c., which may be neat's foot oil or Japan wax, may be emulsified with the aid of the protein-acid condensation product; or the neat's foot oil may be lightly sulphonated.  Blood, albumin, and shellac may also be added.  The finish may be fixed by treatment with formaldehyde or chromium salts. A coloured coating may be followed by a glazing layer of similar composition from which the pigments are omitted.

Title: Method of and apparatus for hobbing gear wheels or the like toothed elements
IPC: B23F23/12
Filed: 1956-06-21
Abstract: 841,259. Gear-cutting. PFAUTER, M., PFAUTER, G., and PFAUTER, H. June 21, 1956 [June 21, 1955], No. 19254/56. Class 83 (3). A method of hobbing gears comprises simultaneously relatively feeding the hob 13 and workpiece 46 axially of the work and tangentially thereto, and imparting a compensating rotation to the work. The gear blank is mounted between a vertically-adjustable tailstock H and a rotary table T, both carried on a slide S. The hob-carriage 36 is traversed vertically on a column ST. The work-table driving-worm 7 is driven through a differential gear 47 and a shaft 6 by a motor 1, which also rotates the hob 13 in bearings on a slide 38 through a shaft 61, spur-gears 10 and a shaft 39. A worm 14 on the shaft 6 rotates feed-change gears 16, 16<SP>1</SP> and a member 24 of a clutch 19, which can be engaged to rotate either a screw 23 to feed the hob axially of the work, or a screw 33 to move the hob-slide 38 across the carriage 36 so as to feed the hob tangentially of the work. In its central position, however, the clutch 19 causes simultaneous rotation of both screws 23, 33. The additional rotation of the work to compensate for the tangential feed is obtained from the gears 16, 16<SP>1</SP>, through gears 49<SP>1</SP>, 50, and the differential gear 47. The cutter-movements produce inclined marks 102<SP>1</SP>, Fig. 2, on each tooth, the angle-of-inclination being controlled by altering the ratio of the change-gears 26, 261 in the drive to the screw 33, the gears 26, 261 being situated behind a cover 56. The method of cutting results in all gears of a series being identically machined with respect to the relationship between, say, the tooth-positions and a hub keyway, as distinct from the graded offset which occurs when a hob is shifted axially after each gear has been cut. By using a modified hob, crowned teeth can be produced, the gearing being arranged so that the width of the hob is used completely while traversing the width of the work.
